Program to Generate Multiplication Table

In this article we will see how we can generate multiplication table.

Multiplication Table is something which produces result of multiplication of a single number with other numbers starting from 1 to 10 generally. But multiplication also possible with other numbers after 10.

For example :

  This is the multiplication table of 7.  
    7 * 1 = 7
    7 * 2 = 14
    7 * 3 = 21
    7 * 4 = 28
    7 * 5 = 35
    7 * 6 = 42
    7 * 7 = 49
    7 * 8 = 56
    7 * 9 = 63
    7 * 10 = 70

We will see two different approaches to get the multiplication table of a number.

By using for loop
By using while loop

Note: In this article we will see getting multiplication table upto 10.

Method-1 : By using for loop

By using for loop we can get the multiplication number.

Approach:

Take a number(static input or dynamic input)
Multiply the number with 1 to 10 by looping.
For looping from 1 to 10 for loop used.
Print the multiplication result one by one.

class Multiplication 
{
    public static void main(String[] args)
    {
        // This is the number of which we will get the multiplication table.
        int num = 6;
  
        // We will get the multiplication table from 1 to 10 
        // Here for loop used for looping
        for (int i = 1; i <= 10; i++) 
        {
            // printing num*i
            // where 'i' is the ith multiplication
            System.out.println(num + " * " + i + " = " + num * i);
        }
    }
}

Output:

6 * 1 = 6
6 * 2 = 12
6 * 3 = 18
6 * 4 = 24
6 * 5 = 30
6 * 6 = 36
6 * 7 = 42
6 * 8 = 48
6 * 9 = 54
6 * 10 = 60

CASE-2
7 * 1 = 7 
7 * 2 = 14 
7 * 3 = 21 
7 * 4 = 28 
7 * 5 = 35 
7 * 6 = 42 
7 * 7 = 49 
7 * 8 = 56 
7 * 9 = 63 
7 * 10 = 70

Method-2 : By using for loop

By using for loop we can get the multiplication number.

Approach:

Take a number(static input or dynamic input)
Multiply the number with 1 to 10 by looping.
For looping from 1 to 10 while loop used.
Print the multiplication result one by one.

class Multiplication 
{
    public static void main(String[] args)
    {
        // This is the number of which we will get the multiplication table.
        int num = 4;
        int i=1;
  
        // We will get the multiplication table from 1 to 10 
        // Here while loop used for looping
        while(i <= 10)
        {
            // printing num*i
            // where 'i' is the ith multiplication
            System.out.println(num + " * " + i + " = " + num * i);
            // incrementing i
            i++;
        }
    }
}

Output:

4 * 1 = 4
4 * 2 = 8
4 * 3 = 12
4 * 4 = 16
4 * 5 = 20
4 * 6 = 24
4 * 7 = 28
4 * 8 = 32
4 * 9 = 36
4 * 10 = 40

CASE-2
5 * 1 = 5
5 * 2 = 10
5 * 3 = 15
5 * 4 = 20
5 * 5 = 25
5 * 6 = 30
5 * 7 = 35
5 * 8 = 40
5 * 9 = 45
5 * 10 = 50
